Hi Rob, all,

Cloudflare is now running an ECH test server here:
https://crypto.cloudflare.com

We're running draft-ietf-tls-esni-09. The HTTPS resource record containing
the current ECH config is available in DNS.

Please let me know if you observe any bugs or otherwise have issues. Our Go
implementation can be found here:
https://github.com/cloudflare/go/tree/cf/src/crypto/tls

Thanks! And for those in the US, happy inauguration day!
- Chris P.
